To all whom it may concern."

Be it known that 1, JOHN A. HoLrELnnR, a citizen of the United States, residing at Uniontown, Fa ette county, and State of Pennsylvania, ave invented certain new and useful Im rovements in Connections for represented in the following specification and the accompanying drawingaiorming a part of the same.

The present invention relates to an improvement in a cast iron wall radiator secsides; requiring the connecting u r tions ma be placed ini contiguity,

.a connecting. nipple.

set upon the contiguous sides, and the bolts extended through the tubes upon-such contiguous sides for clampingthe nipples in their sockets.

In the present invention, 1 fornreach of the marginal tubes adjacent to the corners.

sleeve formed 'therethrough, of the sec and. a bolt sleeves andsides of the with an integral whereby the long or short sides.

extende through such tubular secured by nuts upon the inner marginal tubes, to clamp the sections to? necting bolt.

gether. v i ,I 1 The inner ends of the tubular sleeves are preferablyrrecessed, and loose-nuts fitted-in such recesses flush withtheinner sides of the. the nuts are who1ly 'con 'cealed-,;,and thebolts serve to'connect the sections withoutexposing visibly the meansof connection. I

The invention will be understood by referonce to the annexed drawing, in which Figure 1 is a side elevation of two sections havin ,their ends coupled together; Fig. 2 is a'sectron'of the part adjacent to. the oint, taken" on line 2 -2 in Fig. 1, with the con- Fig.3 is -a'I-cross section .on line 3;-3 i Fig. 1; Fi'gA-{is a section on line Y 5 is a side elevation of three sections having their sides coupled together. Eachradiator section'is shown. of oblong rectangular form, madeof. cast ironin one corners, uponjthe 3 f .a and f piece, with four marginal tubes, two-sidetubes a, a, and two end-tubes b, I); These marginaltubes are united attheir corners by enlargedheads c, the

the twoinner sides of the heads, and the two outer sides of the heads forming seats, in

made to receive. .9. us -nipple 6. Such socket'sare formed in t e seats as will enable the sections tobe connected in the desired relation, whether by their long or short sides;

tubes being joined to' j either'of which a taperin socket'd may be the other seat 0 upon each head remaining unperforated, as shown in Fig. {2.

The tubes b are shown connected by a tube intermediate to the tubes a, and the'tubes intermediate to the tubes b but having free intercommunication as is common insuch wall sections. The tubes g are shown of .difierent'shapes i n FigsQ 1 and 5'. i Fig. 1 shows the'ends of two. sections conjoined by the-push-nip'ples and-by means of bolts h which are extended through passages b transverse to thetubes b, and engaged with nuts 'i which are sunk in recesses 3' formed upon the inner sides of the tubes.

Sleeves 7c are cast in both of the marginal tubes adjacent to the corner heads to form the passages b where the bolts pass through the tubes, to preventthe leakage of heating fluid, and the wall ofthe tube upon its inner side is formed with a block or thickening iece l in which the recess 3' for the nut is are connected by numerous tubes g ormed. The bolt-is formed with right and left hand'threads upon its opposite ends, and

with a hexagonal collar m at the center which lies between theadjacent pipes 1) upon the two sections, where an open wrench can be applied to turn the bolt, and the turning of such collar rotatcsthe bolt in bothof the nuts simultaneously and thus clamps the sections firmly together, and makes a tight joint with the nipple e in the sockets '11.

By recessing the nuts upon the inner sides of the tubes b,.the disfigurement of the sec tion is prevented, and the means of connecting the several sections together is almost wholly concealed, as the collar m and central portion of the bolt are theonly parts of the fastening exposed to view.

By forming the sleevesg in the tubes 0 as well as in the tubes 6, as shown in Fig. 4, the

by the ends, as shown in Fig. 1,- or by y when bored therein.

push-nipples e being made in the corners upon the sides or ends, asmay be required; and the metal in the outer side of each head being madeof sufiicient thickness, is shown at c in Fig. 4, to form the tapering socket The seetlons may thus be carried in stock with the sleeves extended through the sideiand end-tubes adjacent to the headsn, and then fitted up at very short notice for cou ling together by either the sides or ends, y boring the holes required for the tapering sockets d, where required.

Having thus set forth the nature of the invention what is claimed herein is:

A radiator wall section-of rectangular form having four side-tubes and heads upon the cornerswith seats for sockets upon the twoouter sides of the head, one seat 'upon each corner having a nipple-socket therein,

and integral'sleeves extended through the radiator-tubes upon all the four sides ad- I'acent to the corners, adapting either the ong or short sides of such sections to be placed in contiguity to form a wall radiator.

2. In a wall radiator, sections of rectanguiar form having the marginal tubes 0 and united by heads, 0 at the corners/seatsfor outwardly flared sockets upon the outer sides of the heads with sockets formed in the adjacent seats, push-nip les fitted in 'the said sockets, the longitudinal tubes f between the tubes a, the plurality of tubes g connecting the tubes aand and each of the marginal tubeshaving ad aoent to the corners the integral sleeve 70 formed therethrough, whereby the long or short sides of the sections may be placed in c'onti uity and a bolt 7 extended through the tubu ar sleeves and secured by nuts upon the inner sides of the marginal tubes, to clamp the push-nipples in their sockets. I 3. In a Wall radiator, sections of rectanularform having the marginal tubes a and liunited by heads 0 at the corners with sockets for fluid connections u on the contiguous sides of the heads, nipp es fitted to such sockets, the longitudinal tube between the tubes 0, and the plurality of tu es 9 connecting the tubes, at and f, and the marginal tubes having adjacent to the corners theintegral sleeves 7c formed therethrough and the sleeves formed u n the inner sidespf said mar inal tubes with the recesses j, loose nuts 1' tted therein flush with the surface of the tubes, and the bolt h reversely threaded at opposite ends and fitted to the nuts, to clamp the nipples in their sockets.

' In testimony whereof I have/hereunto set myhand in the presence of two subscribing witnesses, on Se tember 6th 1907.
